Abstract (en)
[origin: EP0569754A1] The invention relates to a method and apparatus for determining the effectiveness of filters for filtering air, gases or liquids on filling and sealing machines or the like, in particular during sterile air processing with the aid of a filter system incorporated in the sterile air system of the filling and sealing machine. The system has an aerosol generator (10) and a particle measuring instrument (11). One side of the filter (3) is acted on by a test aerosol and particles in the emerging air stream are measured on the other side of the filter. Such a filter test can be carried out with high reliability in an in-line method rapidly, simply and conveniently at any time. <IMAGE>
